Irishman Cillian Murphy known to his friends as Silly went for a job interview for a computer manufacturing company.
Silly went along to the interview with his brother Mick who also applied for the job.
The Owner of the factory interviewed them both at the same time and said "I am going to give you a test and the one who gets the most answers right gets the job."
After the test the factory owner said "You both got 9 out of 10 but I am going to give the job to Mick". Silly protested "why!". The factory owner said "Well on the question you both got wrong Mick said I don't know this,and you said neither do I".
The factory owner shook his head as Silly and Mick left saying "I knew that guy Silly was not right for the job,when I asked him did he know about Nano Technology he thought it was nannies making the breakfast serial Shreddies".
